October 27, 2009 ECEN 325 Homework #6 Hints Instructor: Sam Palermo For a circuit such as the following: In order to plot Rin, run an AC simulation and plot DB(V(Vi)/I(C2)). V(Vi) is the voltage at the transistor base and I(C2) is the input current. Plot it in dB (same as dB Ω). In order to plot Rout, it is easiest to make a copy of your original schematic and edit it by

Unformatted text preview: removing the input source (grounding it), removing the load resistor and replacing it with your Rout test voltage source, as shown in the following: In order to plot Rout, run an AC simulation and plot DB(V(Vo)/I(C4)). V(Vo) is the output test source voltage and I(C4) is the current going into the output node. Plot it in dB (same as dB Ω)....
